I (0112-88) I v 17 Claims.

This invention is a novel improvement in chimney copings: or tops, and the principal object thereof is to provide novel means for protecting the tops of chimneys from water and frost which ordinarily seeps between the lining and brick or masonry exterior at the top thereof and which seepage has heretofore been a great source of trouble and expense. y

The principal object of the invention is to provide a novel chimney coping or top which will protect the top of the chimney, and at the same 1time will impart an attractive, appearance there- Another object of the, invention is to provide a chimney copingmade of preformed blocks or elements so designed that it can be readily fitted to any size of chimney top, irrespective of whether the chimney does or does not have an inner lining. p

I will explain the, invention with reference to the accompanying drawings whichillustrate sev eral practical embodiments thereof, to enable others tc adopt and use the same; and will summarize in the claims the novel features of construction,.and novel combination of parts, for which protection is desired.

In said drawings:

Fig. 1 is a perspective view of the top .of chimney equipped with my novelcoping. I

Fig, 2 is an inside perspective View of one corner member of the coping cap detached.

Fig. 3 is a vertical section through the coping showing the adjacent upper portion of a lined chimney.

Fig. 4 is a top plan view'of of the coping base, detached.

Fig. 5 is a vertical section, similar to Fig. 3, but showing the cap member of thecoping cutoff to receive the upper end of alining which protrudes only slightly abovethe outer brick or masonry facing of the wall of the chimney.

Fig. 6 is a vertical section, similar to Fig. 3, showing a modified chimney coping.

Fig, 7 is a, partial front elevation of the base member of the coping shown in Fig. 6.

As shown, the chimney to which my novel coping is applied is of rectangular shape, same consisting of an outer facing of bricks or masonry B, and an inner lining L of desired material withone corner member in the outer facing of the chimney, lining L ex tending upwardly above, the top of the outer facing B, as shown in Fig. 3. However, the coping may be also applied to a chimney which is not lined. I

The coping shown in Figs. 1-5 inclusive comprises base blocks I of widthsomewhat reater than the width of the outer facing B, same ex tending from'the lining L beyond the outer face of facing B, and having a down-turned lip or flange Ia overlying the outer face of facing B adjacent the upper edge. Base blocks I are shown ascomprising corner blocks having downwardly and outwardly inclinedupper' facesfl b to discharge rain and moisture over'the outer face of the flange Ia to deflect the water from the lining L. In the upper inner edge of the base blocks I, adjacent the lining L, is a notch or recess Ic, Fig. 3, for the purpose hereinafter explained. I

Base blocks I may be made of any ceramic or.

plastic material, or may be made of steel or other durable material; and. the blocks may be. made of size or dimension to suit rectangular or other shaped flues, the corner blocks being applied at the corners, andif necessary short straight base sections (not shown) similar in cross-section to the base blocks I, may be inserted between the corner blocks I to suit larger sizes of chimneys to cover the top of the outer facing of brick or masonry B of the chimney around the lining L. Base blocks I are preferably provided with recesses Id in their bottom faces adapted to re: ceive binder C (Fig. 3) of cement, mortar, or the like to .secure'the base. blocks I in position upon the top of the brick or masonry workB.

Upon the base blocks I are cap members 2, of any desired material, such as ceramic, plastic,

I metallic, or otherwise; and as shown the cap members 2 are preferably formed as corner pieces in a similar manner to the base blocks I. Each cap piece 2 has a relatively deep outer wall 2a, the inner face of which directly contacts the outer face of the protruding portion of the lining L. The lower end of the outer wall 2a is notched as at 2b at its outer lower edge to fit Within the notch Ic of the underlying base block I, the upper face of the notch 21) forming a continuation of the upper face of the block I and overlapping same so as to prevent moisture from passing upwardly and inwardly along the contacting faces of the notched portions of the members I and 2, toand between the base I and the lining L. I

At the upper end of the outer wall 20. of cap member 2 is an inwardly extending flange 2c having a bead 2d at its outer end for ornamental and strengthening purposes, said flange 20 overlying the top of the lining L, as shown in Fig. 3. Extending downwardly from the inner end of flange 2c is a shallow vertical flange 22 adapted to contact the inner face of lining L adjacent the upper end, flanges 2c and 2e preventing water and moisture from entering between the outer facing B and the upper portion of the lining L of the chimney or flue.

Preferably the spacing of flange 2e from the outer wall 2a of member 2 would be designed to suit the thickness of the lining L; or a filling could be utilized between the flange 2e and lining L where the lining is of less thickness than the spacing between the inner faces of the flange 2e and the outer wall 2a of the cap 2.

In the outer face of the outer wall 2a of each cap member 2 is a series of spaced horizontal slots 21 disposed opposite notches 29 formed in the inner face of the outer wall 2a, the tops and bottoms of the notches 2f2g being cut at the same angle as the upper face I b of baseblock I so as to form continuations thereof as hereinafter explained; and the depth of thenotches 2f-2g are substantially equal to that of the notch 21) at the lower end of the cap member 2, so that the cap members 2 may be adjusted to suit different protruding heights of linings L by butting off lower sections of the outer wall 211 between the bases of the notches 2f-2g. Thus, the depth of the cap members 2 may be readily adjusted to suit the short protruding height of the lining L extendin above the top of the outer brick or masonry facing B as shown in Fig. 5, the portions of the notch la in base I which is not filled by the tongue on the bottom of the outer wall 2a of cap member 2 being filled with a binder D such as cement, mortar, or the like. Short straight pieces similar in cross-section to the cap members 2 may be interposed between the corner cap members 2, to suit chimneys of larger sizes or dimensions.

In Figs. 6 and 7 a modified coping is shown in which similar parts are similarly numbered. In this modification the base blocks I are cast or formed with hollow portions Ia: and Iy to save weight and material. The downwardly and outwardly sloping top surface lb of base I is provided with closely spaced corrugations or ribs 1g which also extend downwardly over the outer surface of lip of flange Ia, said corrugations Ig terminating a distance short of the upper inner edge of surface Ib an amount equal to or substantially equal to the thickness of the outer wall 2a of cap member 2, the lower end of which is beveled as at 2h to the same angularity as the surface Ib so as to rest flatly thereon. In this modification the inner slots 2g in the outer wall 2a are omitted, but the wall 2a may be decreased in depth by cutting or breaking along the bottoms of the horizontal grooves 2f as previously described in connection with Figs. 1-5 inclusive. The corrugations I g in base I serve several purposes, i. e., they permit an even transverse break when base I must be broken or clipped to adjust same to the length of a side of the chimney; also the corrugations Ig project above the'original surface lb of the sloping top so that their upper ends hold the lower end of cap 2 in place on base I; also the corrugations Ig permit the water which flows down the side of the chimney to pass directly along the troughs formed between the corrugations.

My invention provides a novel coping for chimney tops serving the dual purpose of protecting the upper end from seepage of water, rain, or frost between lining L and outer brick or masonry work B, and further provides a top for the chimney having an attractive appearance.

The corner coping blocks I and 2 may be made of any size or dimension to suit rectangular or other shaped flues; and the same can be used with inner or extra blocks or sections disposed between the adjacent blocks I and 2 to suit or fit the lengths of the sides of the masonry B. Moreover, the coping may be applied to chimneys or flues which do not have a lining L. The particular design of the cap pieces 2 may vary; and I therefore do not limit my invention to the exact forms shown in the drawings, for obviously changes may be made therein within the scope of the claims.
